ISIS has shown an ability to command the allegiance of Muslims who have traveled from a reported 70 countries to join its fight in Iraq and Syria. Now it is calling on those who stayed behind and those who have returned home to take action to “kill the infidel” at home. Reporting from Beirut, Nabih Bulos of the Los Angeles Times writes:
e extremist group Islamic State will drive the United States to its "death, grave and destruction," a spokesman for the militants declared in a recording that also called on Muslims living in the West to kill civilians.

"You will pay the price when this crusade of yours collapses, and thereafter we will strike you in your homeland, and you will never be able to harm anyone afterward," Abu Muhammad Adnani said in a 42-minute speech that both taunted and threatened the U.S.-led coalition combating the Islamic State.

The speech called on Muslims in the West to kill civilians in so-called lone wolf operations planned and executed by a single person.

"Do not ask for anyone's advice and do not seek anyone's verdict," Adnani said. "Kill the infidel, whether he is civilian or military.”

President Obama has taken it upon himself to declare that ISIS is “not Islamic,” but his status as an authority on Islamic doctrine is highly questionable. Quite obviously, substantial numbers of devout practicing Muslims see it otherwise, and they have a number of Koranic verses, which they regard as the literal word of Allah, to support their view.

In other words, the Muslim diaspora is now being weaponized by ISIS, a group with substantial appeal. This raises very uncomfortable questions for advocates of multiculturalism. Of course, many Muslims do not accept the scriptural imperatives to slay the infidel, but some do. Muslim immigration to the United States has been soaring during the presidency of Barack Obama. Cities such as Minneapolis are being transformed by the arrival of substantial numbers of Muslim immigrants, some of whom have gone to fight in support of ISIS.

Is this really in our national interest? People are very reluctant to even consider restricting immigration based on religious criteria. But should ISIS's call evoke a response, how long will that last?
